Psychological peculiarities of auditory cognitive defect when psychopathology

Abstract


Work is executed on faculty of normal physiology of Saint-Petersburg state pediatric medical University of the Ministry of health of Russia and St. Petersburg psycho-neurological dispensary N 1. Of the existing Arsenal of psychophysiological methods in this study, we used the original method of studying perception of auditory images and psychological analysis of the status of higher mental functions in patients suffering from paranoid schizophrenia and control group. With increasing levels of anxiety, both healthy subjects and in patients of any information provided may be assessed as important. In such circumstances, the inhibition processes touch flow reduced and insignificant background is estimated sick longer than healthy. Normal perception clean and noisy auditory images has high identifiability (95 %) and efficiency with latent period of 4.2-8.4 C. Taking into account time for вербализацию a decision and biologically significant effect on the perceived information, this time interval corresponds to the physiological norm. The effectiveness of the perception of auditory images in chronic psychopathology is within 40- 75 %, and the latent period - within 11.2-24.3 with that 2.6-2.9 times exceeds the normative time of identification. Reduction in speed and efficiency of information-analytical activities in psychopathological disorders caused, apparently, by the decrease of the functional state of stem-reticular structures included in the first structural-functional Department of the auditory analyzer. The dependence of the quality of auditory-cognitive activity not only from the functional state of cortical fields, responsible for attention, perception, recognition, remembering, but also on the state of slightly-stem systems of the brain responsible tone and reactivity of the brain. Registered reliable link of functional reduce nonspecific brain systems in violation of the neurophysiological mechanisms of perception.
